Pacific Ocean Boundary Ecosystems http://www.pacific-ecosystems-climate.org

This page provides an overview of the observational and modeling datasets available to POBEX.

Global Observational DataSets: These have at least 20-year time series, often significantly longer. Examples include World Ocean Database 2005, wind and surface flux data from ECMWF and NCEP, upwelling indices, SST data from COADS, NCEP-GTS, hydrography and circulation fields from SODA and OFES (model output), and climate indices such as PDO, NPGO, PNA, AO, NAO and MEI. Satellite data fields and their time spans include CHL-a (and derived productivity) (1997-present), SST (1985-present), SSH (AVISO and NASA data, 1992-present) and surface winds (1999-present).

In Situ Physical Datasets: The table below shows some of the main observational datasets available to POBEX. The datasets span the three boundary region that are focus areas. Some of the data is not directly available to the POBEX PIs and is used through joint analysis with our Japanese and South American collaborators.

Model Datasets: The dynamics underlying climate variability in the Pacific Ocean Boundaries are investigated with high-resolution physical-biological model integrations of the OFES-NPZD and ROMS-NPZD models (see links in the tabs at the top of the page for more information on the models). Preliminary work in the Northeast Pacific and the Peru-Chile current system show that these models have high skill in reproducing the physical-biological variability recorded in long-term timeseries (see figure below).

MODEL DATA POLICY: As part of our POBEX commitment the output of all our model experiment/reanalysis is freely available on the Georgia Tech OpenDAP server - [ OpenDAP link ]. A more detailed description of individual dataset is provided [ here ].

OFES Model DATA POLICY: To access the full version of the OFES model products through the Georgia Tech server you need to fill out a request form at JAMSTEC, Japan - [ data request form ]. A subset version of the OFES products is also available through the Asian Pacific Data-Research Center - [ APCRD ].
